To find the minimum quantity of bookmarks Mark must sell, we can set up an inequality using the given information.
Let's assume Mark sells x bookmarks.
The total sales from the handmade cards would be $20.00.
The total sales from the bookmarks would be $2.50 multiplied by the quantity of bookmarks sold, which is 2.5x.
Mark wants his total sales to reach a minimum of $90.00, so we can set up the inequality:
$20.00 + $2.50x ≥ $90.00
Simplifying the inequality, we have:
$2.50x ≥ $70.00
Dividing both sides of the inequality by $2.50, we get:
x ≥ 70/2.50
x ≥ 28
So the inequality that represents the minimum quantity of bookmarks Mark must sell is x ≥ 28.
Therefore, the correct answer is option D. x ≥ 28.
Mark runs a stall selling handmade cards and bookmarks.
Each handmade card costs $20.00.
Each bookmark costs $2.50.
Mark wants his total sales to reach a minimum of $90.00 through the sale of at least one handmade card and several bookmarks. What inequality represents the various quantities of bookmarks (x) Mark must sell?
A. x ≥ 70
B. x ≥ 36
C. x ≥ 16
D. x ≥ 28
